INK-FOUNTAIN ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Writers, of which the following is a specifica-' tion.

This invention has referenceto ink fountam attachments for typewriters, and its obect 15 to provide a .means whereby the ribon of the typewriter may be reinked at will a without removing the ribbon from the typewrlting machine.

The ribbons of typewriters are customarily rovided with a body of inkcarried by the abric of the ribbon. After such a rlbbdn has been in use for a period of time the ink becomes more or less exhausted and the imprint made by the typewriting machine becomes pale and sometimes practically illegible, because of the want of sufficient ink. This often occurs long before the fabric of the ribbon has become so worn as to be useless, and it then becomes necessary to apply a new ribbon to the typewriting machine, or the exhausted ribbon must be removed from the machine and re-inked. I

By the present invention it is unnecessary to remove the ribbon from the machine in order to re-ink the ribbon, and furthermore, the re-inking of the ribbon is practically automatic, beingaccomplished by the ordinary operation of the typewriter in the act of imprinting with the type of the machine, the rib on-actuating mechanism acting to carry the ribbon into active relation to a supply of nk, so that, as the ribbon is slowly fed along, its active surface becomes re-inked.

It is referable to re-ink the ribbon just prior to its being rolled u on one of the spools of the typewriter, since, y this means, there is ample time for the ink to thoroughly infiltrate the fibers of the fabric of the ribbon and become practically uniformly distributed therethrough. When the ribbon is moving in its active position after being re-inked, it automatically avoids engagement with the inking side of the attachment and passes from the ribbon spool to the type without receiving more ink.

Since a single inking of the ribbon will last for a considerable time, provision is made for are detail views,

locking the means for bringing the ribbon into active enga ement with the inking mechanism, out 0 action at the volition of the operator.

The invention will be best understood from a consideration of the following detail description, taken in connection with the accompanying drawings, forming a part of this specification, in which drawings Figure 1 is a vertical central section through the ink fountain attachment, and so much of a type-writer as is necessary for the understanding of the invention. Fig. 2 is an elevation of the attachment with adjacent portions of a typewriter frame. Fig. 3 is a plan view of the attachment. Figs. 4 and 5 llustrating the lock for holding the attachment out of inking operation.

Referring to the drawings, there is shown a typewriter frame 1, which may be taken as indicative of the frame of any form of type-- writer to which the attachment may be applied, and it may be added that the attac 1- ment may be modified in various respects, to adapt it to diflerent forms of typewriters. It may be stated that in the drawings the showing of the typewriter frame is that of a known form of typewriter. There is also shown a ribbon-spool 2, and a ribbon 3, both of which are of known construction and need no special descri tion. Since both the ribbon spools and t e ribbon in different forms of typewriters vary greatly, it is to-be understood that -the showing of the drawings is largely indicative, and that the invention is not confined to any particular construction of typewriting machine. T

In the particular construction shown there is illustrated an ink reservoir 4, in the shape of a flat container of substantially rectangu lar form in cross section, but, it will be understood that the form of the reservoir may be greatly varied from that shown, This reservoir is formed on its u per face with a longitudinal slot 5, above w liich there is located a strip 6, having at each end an ear 7, matching another ear 8, projecting from the body of the reservoir, and the ears are secured together by screws immediate proximityto the slot 5.

The strip 6 is surrounded by a piece of felt 9 or otherwise, so that the strip 6 may be attached to the reservoir in or other suitable material, indicated at 10,

the space between the longitudinal edges of the strip 6 and the corresponding edges of the slot 5 being suflicient to permit the passage of the felt 10. The free ends of the felt 10, after being gathered together beneath the stri 6, by means of any suitable fastening dcvlces, are then spread out within the reservoir 4, so as to present considerable absorbent surface to a supply of ink within the reservoir. The felt becomes thoroughly soaked with the ink, and, by capillary attraction, the ink is constantly fed to the eX- poscd surface of the felt above the strip 6, reaching the same through the s aces between the strip and the edges of t 1e slot 5, but the snug fit of the felt in these spaces prevents any leakage of the ink from the reservoir to the exterior thereof at these points.

Rising from each end of the reservoir, adjacent to the slot 5, are posts or supports 11, two in number, and carrying at their upper ends a rod 12, secured at its ends to the posts or uprights 11, and connecting the same. Mounted upon the rod 12, adjacent to each post 11, is a three-armed spider'13, the arms being equidistantly disposed .and radial from the axis of the spider. The'free ends of the three arms of the two spiders are mnnected together by rods 14, parallel-with the rod 12, about which latter the frame composed of the spiders and connecting rods 14 is capable of artial rotation, the movement of rotation being limited in each direction by a projecting stud 15, formed on each post 11 and in the path of two adjacent arms of each spider. the extent of rotation in the particular structure shown being about degrees, more or less. Such movement is sufiicient to bring one pair of arms 13 so that the connectmg rod 14 for said arms and the rod 12 are in the same vertical plane longitudinal to both rods as shown in dotted lines in Fig. 1, and in full lines in Fig. 4. This occurs when the frame is at one limit ofits rotative movement, and when it is at the other limit of its rotative movement the parts have moved through an arc of about 60, and are in the position shown in'full lines in Fig. 1.

Each rod 14 is surrounded by a roller 16,

extending substantially throughout the length of the rod 14 between the supporting arms 13 thereof, and these rollers are free to rotate. When the frame is rotated to one hmlt of its travel then one of the rollers 16 is closely adjacent to the u per surface of the reservoir 4, and when the, frame is rotated to the other limit of its travel then two rollers 16 are located equidistant from the upper surface of the reservoir and at a consi erable distance therefrom. On the other side of the slot 5 from the posts 11 the reservoir is provided with two upright ears 17 connected by a rod 18, upon which is mounted a roller 19, similar to the rollers 16 before referred to. The reservoir is also provided with other ears 20, projecting laterally therefrom, and fast upon the ends of yoke arms 21, 22, projecting from a supporting plate or frame 23, having at one end an overturned lip 24 and at the other end an elastic tongue 25, adapted to engage over and under, respectively, the upper and lower edges of a portion of the frame 1 of the ma chine in the particular type shown in the drawing. The plate 23 with its lip 24 and elastic tongue 25 forms a clip structure, by means of which the reservoir may be readily attached to or removed from the frame of the :jpewriter, witl'tout requiring any modi llUtL'Lloll whatsoever of the typewriter frame, or any change or alteration therein, or even the mar-ring of the typewriter structure in the slightest degree. Access to the interior of the reservoir 4 for the insertion of ink therein or for any other purpose may be had through a perforation, normally closed by a screw 26, or any other means for this purpose may be used.

In the use of the ink fountain attachment the reservoir structure and parts carried thereby are applied to the frame the typewriter in substantially the position shown in the drawings, the fountain and its supporting structures being below one of the inking ribbon reels or drums, or spools 2, and preferably, though not necessarily, at the lefthand end of the machine when of the general type illustrated in the drawing. The ribbon 3 coming from the spool 2 is carried down,

around and under the roller 19, thence over the felt-10, constituting the inking pad of the ink fountain, thence under the lower roller or rollers 16, as the case may be, thence upward and against the roller 16, which, in the particular the left-hand ro ler, and finally the ribbon is carried to the guiding mechanism by which it is directed in front of the type levers of the typewriter structure, but as this guiding mechanism is shown in the drawings as of the structure employed in a well known form of a commercial type of typewriter machine, no detail descri tion s herein given.

When the rib on is bein wound u on the spool adjacent to the ing mec anism, then the drag of the ribbon will cause the directing frame, composed of the arms 13 and rods 14 with the rollers 16, to move counterclockwise, as viewed in Fig. 1, to the position shown in solid lines inFig. 1, until further movement is arrested by the stop 15. Under these conditions, one of the rods 14 is brought into the same vertical longitudinal plane as the rod 12, and consequently the ribbon is directed into comparatively close relation to the top of the reservoir 4.. The roller 19 is also in comparatively close relation to the top of the reservoir 4, and this osition shown in Fig. 1, is I relation is fixed. Under these conditions,

the ribbon is caused to travel laterall over the inking pad 10 in contact therewit In the position shown in Fig. 1, the ribbon, after leaving the lowermost roller 16, must ride up over the inking pad 10, and then down and under the roller 19 before assing to the reel or spool 2. The result is t at the ribbon is caused to bear "upon the inking pad 10 with considerable force, and the pressure thus exerted is sufiicient to transfer a portion of the ink from the inking pad to the corresponding. surface of the ribbon, and the ribbonso inked is then wound upon 'the s 001 2 with the inked surface innermost.

he reel or spool 2, as is customary in type writing machines, is actuated positively by connection with the type keys and other like parts, propelled by the operator in the usual operation of the typewriter, and it is this movement of the spool 2 which causes the drawing of the ribbon 2 over the inking pad in contact therewith. The operation of inking the ribbon is therefore simultaneous with the operation of the typewriting machine for the production of typewritten matter, and is, to this extent, entirely automatic. Ultimately, the ribbon is all unwound from the remote spool and is all wound upon the spool at that end of the machine where is located the fountain attachment. When this occurs it is customary to reverse the order of travel of the ribbon by a suitableoperation of the customary ribbon-reversing mechanism, and then the travel of the ribbon is away from the spool at the end of the machine carrying the ink fountain and toward the more re mote spool. As soon as this occurs the drag of the ribbon is reversed, and the guiding frame, made upof the arms 13 and rods 14, with the rollers 16, rotated in a clockwise direction as viewed in 1, until stopped by the lugs or stops 15, when the parts assume the position indicated in dotted lines in Fig.1 1. Now, the roller 16 which was previously in close relation with the upper sur face of the reservoir 4 is caused to move outwardly and upwardly away therefrom, until at a considerable distance above the position first indicated. Now the ribbon has a path of travel above and out of contact with the ink pad 10, as shown in dotted lines in Fig. 1, so that no-ink is transferred to the ribbon from the pad during the'movement of the ribbon away from the ribbon-drurn2 shown in Fig. 1. Provision is made for maintaining the guiding frame 12, 13, in the position-shown in clotted lines Fig. 1, for

an indefinite period. y

In order to lock the iding frame in the inactive osition,-.-t'hat '18 so that the ribbon will not e brou ht into contact with the inking pad in eit er direction of its travel, there is made fast upon one of the posts or standards 11' a headed pin 27, carrying a button 28, capable of sliding longitudinally on said pin and of rotating thereon. This button 28 is constantly urged toward the standards 11 by means of a helical spring 29 on the pin 27, between the button 28 and the head of said pin. The button 28 carries a stud 30, projectingfrom the face of the button remote from that engaged by the spring 29, and there is formed through the post 11 a perforation 31 in the )ath of the stud 30, and when the said stud 30 is brought into coincidence with the perforation 31, then the spring 29 will cause the button 28 to move longitudinally on the )in 27, and so project the stud 30 through the'post 11. The stud '30 is of such length that when projected through the post 11 its free end is in the path of two adjacent arms 13, and'the relation of this stud 30 and the stop 15 is such that the guiding frame is effectually locked against rotation in either direction, but this occurs only when the guiding frame is in the position shown in dotted lines in Fig. 1.

Ylhen it is desired to unlock the guiding frame and ermit its free rotation under the action of t e ribbon to the limited extent provided, then the button 28 is moved along the pin ZTagainst the action of the spring 29, until the stud 30 is withdrawn from the perforation 31, and then the "stud may, by the rotation of the button 28, be brought into engagement with the plain surface of the post 11, away from the perforation 31, so that the stud 30 remains inactive. It is thus within the volition of the operator of the typewriter whether the inking mechanism shall be active or be held in the inactive position. 1
